Preseeded exim configuration

[James Davis <jamesd@jml.net>]

I'd like to have exim working from a preseeded configuration so that
once the install has completed, the system can send me an e-mail to
notify me that it's online. Currently mail from a local account is
bounced to the postmaster, complaining that mailing to remote domains is
not possible.

My exim4-config as it stands is below, I've tried adding more
exim4-config options but nothing seems to change the behavior.

exim4-config    exim4/dc_eximconfig_configtype  select  internet site;
mail is sent and received directly using SMTP
exim4-config    exim4/dc_postmaster     string  jolt
exim4-config    exim4/dc_local_interfaces       string  127.0.0.1

Any thoughts?
